3.1
Reactivity reactivityproperty
The index of the reaction capacity of the pulp (cellulose) is expressed as the difference between the time taken by the same volume of the viscose solution
To represent. The shorter the time, the better the reaction performance.
4 principle
Viscose fiber with a certain amount of sodium hydroxide and carbon disulfide chemical reaction, the formation of cellulose sulfonate. Determination of cellulose
The difference in the time taken by the sulfonate solution to pass through the same volume of the filter hole.
5 reagents and materials
